Laser pointing apparatus and on-fulcrum drive apparatus

A laser pointing apparatus for pointing a laser beam on a predetermined position, said apparatus comprising:

• a mirror extending on a X-Y plane and having a mirror surface for reflecting the laser beam;
• a mirror holder arranged so as to be displaceable and having a mirror holder main body for holding the mirror and at least three arms extending outwardly from the mirror holder main body;
• an elastic support mechanism for supporting the mirror holder main body according to the displacement of the mirror holder around a point on a Z axis passing through the center of the mirror and vertically intersecting the X-Y plane;
• a base for supporting the elastic support mechanism;
• coil type electromagnets (hereinafter, referred to as coil magnets) arranged on the respective arms so as to generate a line of magnetic force in the Z axis direction;
• and
• permanent magnets provided on the base facing the corresponding coil magnets so as to generate a line of magnetic force in the Z axis direction,
• wherein a magnetic force generated by interaction between the permanent magnets and the coil magnets supports the mirror holder in such a manner that the mirror holder can be translated in the Z axis direction and also rotated around the mirror center.
